* Apple states that the two high-performance cores are 15% faster and 50% more energy-efficient than the Apple A11's, and the four high-efficiency cores use 50% less power than the A11
* Apple states that the two high performance cores are 20% faster with 30% lower power consumption than the Apple A12's, and the four high efficiency cores are 20% faster with 40% lower power consumption than the A12's
* A14 is capable of delivering up to 11 Trillions of operations per second. So, the AI performance of the iPhone 12 processor with the A14 chip is going to be 83% more than the A13 chip
* A15 contains 15 billion transistors, a 27.1% increase from the A14's transistor count of 11.8 billion. It includes dedicated neural network hardware that Apple calls a new 16-core Neural Engine. The Neural Engine can perform 15.8 trillion operations per second, faster than A14's 11 trillion operations per second (+ 43%)
